cavity

The advantage and disadvantage of measurement of propeller - induced pressure by using different equipment is discussed . the method to obtain self - propulsion point for full scale in depressurized towing tank is studied . the measurements of pressure of two propeller models are carried out , the results of the measurement agree with those obtained by cavitation tunnel very well , which proves this measurement is successful , and the theoretical prediction is verified too 比較了不同測試設備用于螺旋槳脈動壓力測試的優缺點,探討了在減壓拖曳水池中實現實船自航點的方法,并進行了兩只螺旋槳模型的脈動壓力測試,經與空泡水洞中脈動壓力的測試結果進行比較,說明該項測試是成功的,同時也對脈動壓力的理論預報結果做了驗證。

The propeller cavitation range determined by calculation method presented in this paper agrees with the observation result of cavity image at cavitation tunnel very well , which proves the practicability of this method 應用本文計算方法確定的螺旋槳空泡范圍經與空泡水洞中的空泡圖象觀察結果比較,證明了該方法的可行性。
